Michael already posted the "correct answer", and that's what I'm slowly
migrating towards, myself.

But the best way I've found before that was install it in a specific
subtree of my ~ (that way I don't need root at any time), and manage
PATH semi-automatically, as follows:

1. make a symlink in ~/bin to each subdirectory containing programs.
For example, if I install foopkg in ~/foopkg/ and the foo program is
~/foopkg/bin/foo , I symlink ~/bin/foopkg -> ../foopkg/bin .

2. this snippet very early in my .bashrc adds each such subdirectory to
the PATH:

case $PATH in
(*/rc-scripts*)
:
;;
(*)
PATH=$PATH:$( find ~/bin -type l -xtype d | paste -sd: )
;;
esac

The first case is there to prevent recursion, as I know that rc-scripts
will always be one of the symlinks.

Don't, write an ebuild for it.

With access to the kernel sources, you doesn’t have to remember what
the others do, see
‘/usr/src/linux/Documentation/admin-guide/sysrq.rst’.


This file doesn't exist on my system (not even the directory
"admin-guide").

I can find it under:

/usr/src/linux/Documentation/sysrq.txt
That’s interesting, I doesn’t expect that. Maybe we are using different 
kernel sources. Mine is ‘sys-kernel/gentoo-sources-4.10.12::gentoo’ but 
wait, I’ve found it also under ‘Documentation/sysrq.txt’ with version 
4.9.16 and it’s slightly a little bit different (in form not in content 
as far as I can see).


But in my case I even had no access to any file, because no command
was working anymore. So I think it is better to have these information
on a good old sheet of paper. ;-)
Ha, yes of course, a paper backup beats them all (under typical 
circumstances). ;-)

[gentoo-user] How do you manage manually compiled software?

[Danny YUE]

Hi guys,

I am compiling RISC-V tools...I am just curious how do you manage your
manually compiled software? Here are some options:

1) Just "make install" everything into /usr/local. But if the Makefile
does not have removing option, how do you remove it then?

2) Put compiled software into /usr/local/some-dir, then create symbolic
links to /usr/local/some-path. But this does not work if the software
relies on some environment variables (well, you can set it in .bashrc
but it then loses flexibility).

3) Just install it anywhere and change PATH. To be honest, I don't
really like this way because changing the PATH requires extra actions,
e.g. open another terminal.

Any idea?

[gentoo-user] printer recommendation

[thelma]

I need to replace one of my Brother printers and am looking for a
replacement.  I have had luck in recent years with Brother printers:
- HL-5250DN (needs to be replaced)
- HL-5370 - working OK

I only need a B/W printer with an Ethernet interface. Toner usage is
important. Average pages per day will range from 20-50.

Brother recently improved with their Linux drivers; installing one under
Gentoo from RPM (with minor adjustments) was ok.

Looking at Brother web-page, they have:
- HL-L5200DW - 8000 pages per $177.49 toner seems OK
It has "Advanced security features to help protect sensitive documents"
I don't know what that is, have to ask Brother.
However, http://www.openprinting.org/printers/manufacturer/Brother
does not mention this model, so I have no reference as to how well it
works with Linux.

HL-L2360DW - Seems OK but it only makes  2,600-pages per $100/toner;
this is NOT OK.

I used to have HP but I don't like their toners with chip technology, so
NO HP, unless they have changed.

Any other recommendations?

I have it on a small post-it-note stuck on the side of my monitor.  I'm
not sure, may have been Neil or Alan, that posted it this way.

Reboot Even If System Utterly Broken. 

That sort of stuck with me.  Still, I look at the sticky note to be
sure.  I found it on linuxhowtos.org which ironically, was translated
from a site in your language I think.  lol 

Anyway, it's handy to have around, just in case, and a little safety is
needed when it seems the Sun just went dark.  I wish I had that when I
did the hal thing.  Let's not go to far into that tho.

R resets the keyboard. E sends a SIGTERM to all processes except PID1,
which is why you need to restart services after pressing it. I sends a
SIGKILL similarly. As you say S syncs ass filesystems, U unmounts
filesystems and remounts them readonly and B reboots.

Once you have got to E, you need to restart stuff. You may get away with
switching runlevels to bring up all your services, or you may decide that
once the system has got itself into a state that has you reaching for
SysRq, a reboot is in order.

It's rare that I have to go "all the way" with this but at least it does
flush things through the system and properly unmounts file systems
first.  That alone is some comfort.  I switched to ext4 which is
supposed to handle those things pretty well BUT why risk it if you can
unmount them properly, even if it is brute force. 

One thing about alt sysreq, once you get to a certain point, you have to
go "all the way" with it.  I've found that just the R and E generally
gets things back to a point it is accessible and I don't have to go
through it all.  I think once you get to the I or S, it's all or nothing
at that point.  Even after the E, you may have to start/restart some
init processes.  FYI, I'm pretty sure the S is what syncs the file
systems and the U unmounts everything.  Of course, the B reboots.  I
can't recall what the others do exactly.

I wonder if some guru that is familiar with this could shine some light
and share some wisdom.

Hi Dale,

thanks for this hint. Although I know about this "magic stuff", I don't
even have it enabled in my kernel. At the moment I'm happy that my 
system is working again so that I can do some other urgent tasks. But 
I will look closely at these function within the next time. Even when 
it is not possible to "repair" the system in the case of a crash, it is 
helpful to be able to write the cache to disk and reboot the system.

I wonder if this is related.  When I did my switch, I hit a point where
I had to start the alt sysreq key sequence.  I only had to do the R and
E part to get my console back tho.  At the time, I thought it may just
be some weird occurrence but now I wonder if it was related to some
update.  Once I got my console and login screen, I was able to login and
carry on, after getting all the services back running that got killed
off.  I got the login screen back after hitting the E part. 

I wonder, will others run into this sort of problem?  If so, what is the
best way to get back to normal?  For you, rebooting helped.  For me,
just starting the alt sysreq did the trick.  It makes one wonder.

Hi,
"Invalid Machine command" (forgot the exact error message) usually happened to

Can't execute it. "Invalid command".

There is one terminal (gnome-terminal) still open. This is the one
that I used to recompile everything. I'm logged in there as root.
But I cannot open another terminal. I don't even see what I'm typing
(no echo). I can only see the output.

AFAIK I don't have any binaries installed on my system.

seems that everything works well again.

I wonder what caused the trouble. The last package that was
compiled successfully was media-plugins/frei0r-plugins-1.5.0.
The next package, which failed, was media-libs/libmypaint-1.3.0.
After that, the system was broken.

Now I resume the emerge process. 15 Packages are left. Right now
media-libs/libmypaint-1.3.0 was successful compiled. Waiting
for the rest.

Thanks for all answers.

Can't execute it. "Invalid command".

There is one terminal (gnome-terminal) still open. This is the one
that I used to recompile everything. I'm logged in there as root.
But I cannot open another terminal. I don't even see what I'm typing
(no echo). I can only see the output.

I don't know how to repair it because I don't know what exactly is 
broken. At the moment I can at least ask the M/L. I don't wanna lose
also this possibility.

I will wait for some time. Maybe someone else can give me a hint. If
not, I will reboot the system.

Did you run the revdep-rebuild command?
Keep running that until it completes succesfully.

[gentoo-user] System borked after emerge -e world

[wabe]

Hi folks,

it seems that my system is broken after recompiling everything with 
the new gcc5.

I even cannot execute any command or start new programs. It is also 
not possible to open a terminal or to login on console.

When I type something in an already opened Xterm it says "Ungültiger 
Maschinenbefehl" (in English probably something like "invalid machine 
command").

On tty12 I can see messages like this:

traps: ls[4055] trap invalid opcode ip:3cd3d91e024 sp:3d6a804abb0 error:0 in 
libc-2.23.so[3cd3d865000+19d000]
grsec: Illegal instruction occured at 03cd3d91e026 in /bin/ls[ls:4055] 
uid/euid:0/0 gid/egid:0/0, parent...

kernel is 4.8.17-hardened-r2

(uname -a is still working).

I don't dare to reboot my system because I'm not sure that it will boot.

I don't even know if this email will reach the list, because claws mail 
also dropped some errors about "bogofilter doesn't work".

Any help would really appreciated.

If your system doesn't support python 3 then that is arguably the
larger problem and you should get it fixed before you are *forced* to
get it fixed when support is dropped.

I'm not exactly sure what timing something *inside* the terminal will
accomplish, as it's very possible that all writes will be passed to
buffered, memory mapped areas. In essence all that would be timed is
the system calls and any time the programs spend processing their
input, not anything that the terminal emulator has any control over,
like rendering and scrolling speed. In any case try running the tests
a few times to see if the files (including the executables) are cached
and the operations complete more quickly.

If terminal emulators differ in anything but their rendering speeds I
would be extremely surprised, as that is really all they do. The
suggestion to look for compositing is a good one. I suggest the
useflags "egl gles gles2 opengl" (or some variation of that) to make
sure acceleration is enabled for every program that can use it.

As an aside, the above useflag changes and some others are on a list
of things I think should really be added to the handbook - they're
basically essential for a usable system on most hardware now.

I'm curious what true-color support actually _does_ in an ANSI
terminal emulator.  The ANSI escape sequences only allow for 16
colors.

I second the recommendation for rsnapshot.  I've been using rsnampshot
for several years to backup stuff to an external Firewire RAID array.
The really convenient thing about it is that backup is simply a set of
directory trees that you can peruse at any time to verify that backups
are occuring or to look at old versions of files.

Walter,

That flag "-D_GLIBCXX_USE_CXX11_ABI=0" is a CPPFLAG. It is only
recognized by GCC 5.1.x and higher. And it only works on GCC built with
dual ABI support. Gentoo doesn't support the dual ABI builds.

Info links :
https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_macros.html
https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html#abi.versioning.__GLIBCXX__
https://gcc.gnu.org/onlinedocs/libstdc++/manual/configure.html

On my system, I went ahead with the switch to GCC 5.4.0.

The "-D_GLIBCXX_USE_CXX11_ABI=1" CPPFLAG forces GCC to check IF the new
ABI should be applied FIRST. NO FORCING the ABI on software that doesn't
use it.

Putting CPPFLAGS="-D_GLIBCXX_USE_CXX11_ABI=1" in make.conf killed almost
all the erorrs in the revdep-rebuild process.

Putting that in as a CFLAGS or CXXFLAGS switch caused lots of errors in
revdep-rebuild.

Thought you might want to know.

I too run custom rather than gentoo kernels on my system with
/usr/src/linux being a symbolic link pointing to the location of the
kernel sources I have in my $HOME directory for this very reason.

you could set the symlink IUSE for your kernel package, that way your

It does not directly help with the consistency problem, but Elogv 
(https://wiki.gentoo.org/wiki/Elogv) at least helps to keep track of the 
messages portage prints out. You could, for example, decide to not

The ebuilds are using an obsolete eclass. You can ignore the messages if
you don't use any of these ebuilds, but it you do try to emerge one of

The reason I mentioned gentoo-sources on the command line is that I'd 
already tried revdep-rebuild without mentioning it, with the same result 
(gentoo-sources emerge started), and I was trying to prevent it and avoid 
the waste of resources.

Nope. I tried that too. I just had to wait while all that pointless work was 
done again.

Re: [gentoo-user] In search of an truecolor-capable terminal emulator

[Guy-Laurent Subri]

Hi,
I'm using 'simple terminal', better known as st.

Here's the link to the website: http://st.suckless.org/
And here's also a link if you want other terminals that support
truecolors : https://gist.github.com/XVilka/8346728

Have a nice day!
